March 11 (UPI) -- Air India is urging travelers to "use lavatories only for purposes they are meant for" after a flight to Delhi returned to Chicago due to eight of its 12 toilets becoming clogged.

Air India AI126 was about five hours into its flight from Chicago to Delhi last Wednesday when the decision was made to return to Chicago as a result of the eight clogged toilets.

Once the plane landed, workers discovered the clogs had been caused by flushed items including plastic bags, rags and clothing items.

An Air India spokesperson said in a statement provided to The Times of India that the airline wishes to "urge passengers to use lavatories only for purposes they are meant for."
